Meet the devoted wife who gave up everything and decided to move into an aged care facility with her husband of 68 years after he was diagnosed with dementia.

Beryl Wykes and her husband Ossie gave up their family home and beloved garden when he fell sick in 2014 and moved into the Whiddon Laurieton facility on the mid-north coast of NSW.

The couple, who were 19 and 21 when they first met, say sharing happy memories together is the secret to a long happy marriage - something that has become more difficult since Ossie's diagnosis.

To help ease the transition into the aged care facility, the team at Whiddon Laurieton organised for the couple to be able to create a secret garden in a space next to their new home.

'Ossie and I have always been keen gardeners; I love flowers and grew things from an early age, whereas Ossie always grew vegetables, especially onions, tomatoes and beans,' Mrs Wykes siad.

'Watching our gardens grow together with our family has always been one of my fondest memories of our marriage.'

The space they have transformed helps calm Mr Wykes and allows them to reminisce.

'I feel fulfilled when I am gardening and I know that its calming effect has been enormously helpful for Ossie.

'Sometimes we can speak about his trucking business and times catching Murray Cod on the Darley River while I potter away.

'Or he laughs as he remembers moments like the time I made a blackberry pie, but dropped it on the floor after it was taken out of the oven. The pie stained the floor and stayed there until we sold the house.'

The couple first met in Wellington in NSW while they were staying with family.

Mrs Wykes said when she first spoke to her future husband from across the fence, she immediately liked him for his curly hair and friendly personality.
